GENERAL DESCRIPTION
The SDX series sensors will provide a very
cost effective solution for pressure appli-
cations that require small size plus per-
formance. These calibrated and temperature
compensated sensors give an accurate and
stable output over a 0 to 50°C temperature
range. SDX devices are available in standard
commercial and prime grades to allow optimi-
zation of accuracy and cost in any given appli-
cation. This series is intended for use with
non-corrosive, non-ionic working fluids such
as air, dry gases and the like.
Devices are available to measure absolute
and gage pressures from 1 up to 100 psi.
The absolute devices have an internal
vacuum reference and an output voltage
proportional to absolute pressure.
Scale:
1 cm
½ inch
The output of the bridge is ratiometric to the
supply voltage and operation from any D.C.
supply voltage up to +20 V is acceptable.
The SDX devices feature an integrated circuit
sensor element and laser trimmed thick film
ceramic housed in a compact solvent resis-
tant case.
The package is a double wide (i.e., 0.600"
lead spacing) dual-inline-package. This is the
same familiar package used by IC manu-
facturers except it is only 0.470" long and
has a pressure port(s). The PC board area
used by each DIP is approximately 0.26
square inches. This extremely small size
enables the use of multiple sensors in limited
available space. The DIP provides excellent
corrosion resistance and isolation to external
package stress.
The DIP mounts on a PC board like a standard
IC with through-hole pins. The pins anchor
the pressure sensor to the PC board and pro-
vide a more secure and stable unit than other
types of packages.
